The present invention relates to an oil filter, and in more detail, using two springs having different spring constants configured inside a fixed housing and high pressure cutting oil or cutting oil, etc., self-cleaning of impurities remaining in the filter without separate filter decomposition It relates to an oil filter that can be.

In general, in a machine where cutting is performed in an industrial field, cutting oil such as oil is used to prevent deformation of the workpiece, to clean and lubricate the workpiece, to cool the tool, and to improve cutting performance, such as dust mixed with the cutting oil, An oil filter is used to remove the cutting chips, impurities and the like to provide a purified cutting oil free of harmful elements.

When the cutting oil is used to remove unnecessary parts by cutting tools during cutting operations such as mechanical workpieces, chips of a predetermined size or more are discharged or separated separately by a conveyor device, but fine chips are not separated and discharged into the oil storage tank. The cutting oil, which is collected and stored, including the fine chips, is transferred through various kinds of liquid delivery pumps to perform the purpose again.

Meanwhile, the cutting oil provided in the oil storage tank passes through an internal filter formed inside the oil storage tank, is transferred through a delivery pump to reach an oil filter to filter the cutting oil through the oil filter, and the filtered cutting oil is a workpiece to be processed. Will be transferred.

However, when the liquid delivery pump sucks the cutting oil of the oil storage tank, the fine chips included in the cutting oil must be mixed into the pump as it is and transferred. Therefore, the flow path of the cutting oil is transferred through the cutting oil supply path to the workpiece. The blockage of one part of the pump caused an overload of the pump and the like.

Therefore, since the inflow of cutting oil is not made correctly, the operating efficiency of the machine is drastically reduced and adversely affects the quality of the workpiece, thus requiring the use of an oil filter to filter out such fine chips and foreign substances.

The oil filter used for the above purpose is to periodically clean the oil filter to ensure smooth filtering of the cutting oil and reliability of the quality of the filtered cutting oil, and also to replace the oil filter when worn.

In the maintenance of the oil filter, the filter introduced into the oil storage tank is dismantled and cleaned or replaced, and the replacement of the filter installed with a device that filters the oil sent to the other side more finely also stops the operation of the machine. In this process, the efficiency of the work is lowered and the working time is long, and the impurities in the filter are not completely removed.

In order to solve this problem, a method of cleaning by using ultrasonic waves, cyclone through high-speed rotation, or air pressure to drop foreign substances on the filter surface has been proposed. However, it is cumbersome to have a separate device and power source In addition, there was a disadvantage of high maintenance costs.

In the oil filter of the present invention, which is composed of three parts including a cover part 100, a main body part 200, and a support part 300, a cylindrical shape as a whole,

First, the cover part 100 is formed of a cylindrical upper cover 110 whose lower part is opened and the upper part is closed by a circular plate, and cutting oil inlet and outlet ports through which cutting oil flows in and out of the upper center part of the upper cover 110. 120 is formed, the high pressure oil inlet and outlet 130 through which the high pressure cutting oil to the cutting oil flows in and out is formed in one lower portion of the upper cover 110.

Next, looking at the main body 200 is installed in the lower portion of the cover part 100, the upper spring cover 250 is provided at the top and the cutting oil inlet 211 through which the cutting oil is introduced into the central portion is formed, The cylindrical housing 210 having the upper spring 240, the spring filter cover 221, and the spring filter 220 sequentially provided therein is installed therein.

In addition, a sliding shaft 230 penetrating the upper spring cover 250 is formed inside the housing 210, and is installed on the upper spring cover 250, and the sliding shaft 230 is formed at a central portion thereof. The piston 260 is formed to be penetrated to form the main body 200.

The spring filter 220 is formed of a relatively constant spring compared to the upper spring 240 is configured to easily adjust the gap due to the upper spring 240, the upper spring 240 is a sliding shaft It is formed along the outer circumferential surface of the 230 is embedded between the spring filter cover 221 and the upper spring cover 250 to assist the spring filter 220 to maintain a predetermined interval.

In addition, a groove is formed on the upper side of the spring filter cover 221, which is coupled to the top of the spring filter 220 and slides to adjust the spacing of the spring filter 220, the groove of the sliding shaft 230 into the groove. A lower portion is fitted and coupled, and the piston 260 is fixedly coupled to the upper portion of the sliding shaft 230, and the piston 260 is fixedly fastened by the lock nut 262.

Finally, looking at the support portion 300 is fastened to the lower portion of the main body 200, a circular lower cover 310 is formed in the lower portion of the housing 210 is coupled to support the spring filter 220 The outlet cover 320 is formed to be coupled to the lower side of the lower cover 310, and a cutting oil outlet 330 for discharging cutting oil is provided at a lower center portion of the outlet cover 320.

The oil filter of the present invention having the above configuration provides a plurality of oil seals 222, 231, 251, 261, 312, and 321 inside the oil filter in order to provide a correct flow path of the cutting oil supplied thereto and to prevent separation of the cutting oil. The oil of the present invention may be provided by providing a plurality of fixing bolts 400 for fixing and fixing the cover part 100, the main body part 200, and the support part 300 for the solid structure of the oil filter. When the filter is carried out, it can be formed to have a solid configuration without being separated.

According to the present invention having the above configuration, the oil filter is formed by forming two main components having different spring constants, and the spring filter 220 having a low spring constant serves as a filter for cutting oil, and the upper spring 240 having a high spring constant. ) Is to act to help the spring filter 220 to act as cutting oil filtering to maintain a constant interval, and to describe the operation of the present invention oil filter of the above configuration,

When cutting oil is introduced through the cutting oil inlet 211, chips or foreign substances are blocked by the spring filter 220 by the coil spacing of the spring filter 220, and only the cutting oil from which the harmful substances have been removed is removed from the spring filter 220. It flows into the interior and is collected into a space between the upper cover 110 and the piston 240 through a flow path processed into the sliding shaft 230.

At this time, the high-pressure oil inlet and outlet 130 is blocked by a valve (not shown), and the coolant collected therein is sent out to the desired target through the coolant inlet and outlet 120 by the continuous delivery pressure of the pump, and chips or foreign substances of the coolant The back is sandwiched or remains between the spring filters 220.

When the cutting oil is continuously introduced and filtering is repeatedly performed, residual foreign matter accumulates in the spring filter and thus the filter efficiency is reduced. In this case, the filter should be washed. High pressure oil or high pressure air introduced through the pressure to the piston 260, when the piston 260 is raised due to this, the sliding shaft 230 coupled to the piston 260 is also sequentially raised and the sliding shaft The spring filter cover 221 coupled with the 230 is also raised so that the upper spring 240 is compressed and the gap between the spring filters 220 is increased by the compressed distance.

At this time, the distance in which the piston 260, the sliding shaft 230 and the spring filter cover 221 rises can be controlled by the pressure of the supplied high pressure oil, and thus the spacing between the coils of the spring filter 220 is larger. The chip or foreign matter, which is sandwiched between the spring filters 220, is released, and the cutting oil inlet 211 is blocked by a valve (not shown) to prevent the chip or foreign matter, etc., from leaking out to the outside. It is done.

At this time, when the clean cutting oil is strongly introduced through the cutting oil inlet and outlet 120, the cutting oil is rotated in the rotational direction of the spring to discharge the discharge hole formed in the lower cover 310 together with chips or foreign substances that were sandwiched between the spring filter 220 ( 311 is transferred to the outlet cover 320 and discharged to the outside through the cutting oil outlet 330 at the center of the outlet cover 320, thereby completing the operation of the present invention.

On the other hand, Figure 5 is a view showing another embodiment of the present invention, by removing the outlet cover 320, the cutting oil outlet 330 as shown in the figure, by deforming the outside of the housing 210 to the closed type open type It is also possible to install and use it in a reservoir rather than being installed on the path of cutting oil.

The oil filter of the present invention, which filters the cutting oil in the above-described configuration, functions as an oil filter during cutting, and after cutting, the oil filter supplies self-cleaning by supplying high pressure oil and clean cutting oil from the outside and washing the cutting oil. As long as the deformation of the spring does not occur by implementing the effect that can be used semi-permanently, this has the additional effect of maximizing the economic cost reduction and work efficiency.
